JACK FOR BURNISHING.

SPECIFICATION forming part of Letters Patent No. 439,752, dated November 4, 1890.

Application filed July 26, 1890. Serial No. 360,053. (No model.)

To all whom it may concern:

Be it known that I, HIRAM F. REED, a citizen of the United States, residing at Abington, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Burnishing- Jacks, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of my invention is to produce a jack upon which boots or shoes of various sizes are placed and held firmly without changing the curvature of the sole or straining the upper during the process of burnishing the soles.

The invention consists of an extensible foot-shaped piece pivoted to a leg portion that is supported by a standard and a series of levers within said extensible foot and leg portion, whereby the jack can be adjusted to fit any size of boot or shoe, as hereinafter fully described, and pointed out in the claims. Referring to the accompanying drawings, Figure 1 represents a side elevation of a burnishing-jack embodying my invention mounted upon a standard, shown partly in section. Fig. 2 is a side view of the same, one-half of the covering-plates being removed. Fig. 3 is a section taken on line w 00 of Fig. 2. Fig. 4 is a view similar to Fig. 2, but showing the foot extended. Fig. 5 is a plan or top view. Fig. 6 is a side view of the central levers. Fig. 7 is a view of the under side of thefoot-levers. Figs. 8 and 9 are detail views of the ball and toe pieces. Fig. 10 is a side view, partly in section, showing the foot portion in the position to receive a boot.

A represents the leg portion of the burnishing-last, which is formed in two parts-- that is, divided longitudinally into halveswhich are secured together by screws, as hereinafter described.

B is the heel and shank portion pivoted to the leg portion at a (1. Within the leg portion A are three levers O D D. The central one C is fulcrumed on a screw b, that passes through a hole I), (see Fig. 6,) which is slightly elongated to allow for the upward movement of the foot portion when putting on a boot. This lever is provided with a tail 0, the lower end of which passes through an opening in a belt E, that passes over two rollers E, carried by screws c. The ends of the belt are passed down into a hollow standard Z, upon which the leg portion A is mounted, and one end of the belt is secured to a treadle F and the other end to a spiral spring G, which draws the belt and lever to their normal position after the treadle has been released. The levers D D are arranged on each side of the lever C and are fulcrumed on a screw 01, an elongated opening 01' being formed in the lever 0 to allow said lever to work independent of the side levers O, which are provided with openings 6, through which the screw 1) passes. The lower ends of the levers D D are provided with slots f and are connected to the lever O by pins 9 passing through said slots f. The upper end of the central lever O is, by a bar H, connected to a sliding piece I, to the outer end of which is secured the toe-piece J. This bar is provided with along slot j, through which passes a screw h, that forms aguide for the bar as it is pushed forward or drawn backward.

K is a sliding piece recessed on its under side to receive the sliding piece I. This bar is at its forward end formed with slots it, through which the screw it passes and forms a guide for the piece K, as well as for the piece I, and to the forward end of this slidepiece is secured the ball-plate L, and the rear end is formed with a recess 7c on each side, into which the upper ends of the levers D D pass.

K is a screw that connects the rear ends of the two sides of the heel-piece B together, and also forms a stop for the piece K, which is recessed on its upper side near its rear end at 10 and the movement of the piece K is limited by the end of the recess coming into contact with the screw R The upper end of the leg portion A, into which the heel portion B fits,'is provided with a small stud m on each side, and the heel portion B is formed with a slot at on each side. These studs and slots limit the movement of the foot portion when raised to place a boot upon the last.

The operation is as follows: Ifit is desired to burnish the sole of a shoe, the operator places the shoe upon the last, and thenpresses down the treadle F with his foot, which draws the tail 0 of the lever C in the direction of the arrow, (see Fig. 2,) and the upper end of the lever is thrown forward, and the two side levers D D, being connected to the lever O by the pins g below their fulcrum cl, are thrown forward at the same time, but only for about half the distance of the lever (J. The distance that these levers are thrown forward depends upon the size of the shoe upon the last, the toe-piece J being thrown so to hold the shoe firmly thereon. After the sole of the shoe has been burnished the operator removes his foot from the treadle F, when the parts are drawn to their normal position by the spring G.

.When it is desired to last a boot, the foot portion can be raised up, as shown in Fig. 10, so as to allow the leg of the boot to be passed over, and is lowered as the boot assumes its proper position upon the last.

It will be seen that by reason of the peculiar connection between the levers and the leg portion and the sliding pieces in the foot portion the latter can be raised without in any way interfering with said levers. It will also be seen that the jack is adapted to receive boots or shoes of various sizes and hold them firmly without changing the curvature of the sole or straining the upper, as the toepieces can be thrown forward a considerable distance, the stilfness of the leather being suflicient support for the sole between the toe and ball portion.

What I claim as my invention is,

1. The sliding piece I, the toe piece J,

mounted thereon, the connecting-bar H and lever O, the sliding piece K, the ball-piece L, mounted thereon, and the levers D D, the foot-piece B, and leg A, all arranged and operated substantially as set forth.

2. A burnishing-jack having a leg portion, a foot-piece B, pivoted thereto, a ball-piece L, and toe piece J, mounted upon slides operated by levers, whereby the toe-piece is thrown forward a greater distance than the ball-piece, substantially as set forth.

3. In a burnishing-jack, a foot-piece B,pivoted to the leg A, in combination with a toepiece J, slides I, connecting-piece H, lever O, a ball-piece L, slide K, having recesses 7c, and levers D D, said levers being connected to the lever O by pins g, and the tail 0 0f lever C being connected to a belt E, operated by a treadle and spring, substantially as set forth.

4. A burnishing-jack consisting of the following elements: leg A, foot-piece B, pivoted thereto, ball-piece L, toe-piece J, slides K I, bar I-I, levers C D D, belt E, rollers E, treadle F, spring G, and standard Z, arranged and operated substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 12th day of July, A. D. 1890.

HIRAM F. REED.
